ABSTRACT
Abstract: Petroleum-based phenol-formaldehyde resins have been widely used to produce materials for a wide range of applications. These resins have a huge market in the industry because of the excellent properties and relatively low-cost production and are high-added-value materials. However, the toxicity and the economic and ecological drawbacks of the use of phenol and formaldehyde in the formulation of resins have revealed the necessity to nd less toxic and renewable derived compounds for new bio-based resin elaboration. In this context, the replacement of phenol by other phenolic compounds derived from renewable resources has become a possible alternative to develop more environmentally friendly resins. The use of different lignins, the improvement of their properties, and the different parameters involved in resin formulation have led to extensive research in this eld. In this light, new advances toward lignin-bio-based resins, summarizing different works and the existing challenges for their industrial application, are highlighted in this chapter.
